Solve this problem in details and calculation:

Ext-1.7 (20 points) One side of a rigid, insulated container initially holds 2m3 of air at 27C,0.6MPa. The air is separated by a thin membrane from other side of the container holding 3m3 of air at 327C,0.1MPa. Owing to the pressure difference of the air, the membrane stretches and eventually bursts, allowing the air on both sides to mix r and reach equilibrium both in temperature and pressure. Assuming the ideal gas model for the air, determine (a) the mass of the air, in kg, (b) the final temperature of the air, in K, and (c) the final pressure of the air, in MPa
